Perbandingan uang panji dan yoga adalah 2 : 3.uang yoga 2/5 uang ira.berapa uang masing-masing ?

Jawaban:

a / b = perbandingan

Penjelasan dengan langkah-langkah:

a = uang Panji

b = uang yoga

c = uang ira

a / b = 2/5

a = 2b / 5 atau b = 5a / 2

b / c = 2 / 5 atau c = 5 / 2b

*subtitusi

b / c = 2 / 5

( 5a / 2 ) / c = 2 / 5

(5a / 2) / ( 5 / 2b) = 2/5

(5a / 2) / ( 5 / 2 ( 5a /2 ) ) = 2/5

(5a / 2) / ( 5 / 5a ) = 2/5

(5a / 2) x ( 5a / 5 ) = 2/5

25 a^2 / 10 = 2/5

a^2 = 2(10) / (5x25)

= 20 / 125

= 4 / 25

a. = akar ( 4 / 25 )

= 2 / 5 (uang Panji)

a / b = 2 / 5

(2/5) / b = 2 / 5

b = (2/5) / (2/5)

= 1 ( uang yoga )

c = 5 / 2b

= 2 / 2(1)

= 1 ( uang ria )
